Environmental properties for AVIFORM L50

Several of the de-icing and anti-icing products available today are non-toxic, however they can cause serious damage to the environment in and around the airport.

The environmental impact is mainly linked to the Biochemical Oxygen Demand (BOD) and the time it takes for the chemical to break down. The oxygen demand for de-icers based on potassium formate and sodium formate, like Aviform L50 or Aviform S-Solid, is modest.

Biodegradability and eco-toxicological tests have been performed and AVIFORM L50 conforms with SAE AMS 1435A.

AVIFORM L50 has lower oxygen demand than urea, glycol and acetate-based runway de-icers. At the same time outstanding de-icing and anti-icing results are achieved and the oxygen depletion of soil and surface waters is strongly reduced. Thus diminishing the negative impact of runway winter deicing on the environment without jeopardizing traffic safety.

AVIFORM L50 is not based on chloride and nitrogen salts and is not toxic to humans, animals or aquatic organisms. It is fully biodegradable in aqueous systems without causing a damaging oxygen depletion. AVIFORM L 50 is listed as a non-hazardous component.
